experimental methodology for recycle coarse aggregate

factory sale direct manufacturer strong mixing racking plant

Matec has developed a wide knowledge in the aggregates sector, as our machines for the water treatment were born to work with aggregates, materials which are not easy to handle. This is why we created a range of machines to wash aggregates, to manage the whole process, and to guarantee the best output from the washing system and the water treatment plants.

EXPERIMENTAL STUDY ON THE APPLICABILITY OF RECYCLED AGGREGATE

Two types of recycled aggregate concrete were produced using real ready-mixed concrete plant. Recycled coarse and fine aggregates (RG-RS) and in some cases recycled coarse aggregate and natural sand (RG-NS) were used in concrete production. Recycled aggregate concretes were transported by truck agitator from the concrete plant to work site.

Experimental research on durability of recycled aggregate

The freeze-thaw durability of recycled aggregate concrete has significance for the concrete buildings in the cold region. In this paper, the rapid freezing and thawing cycles experience on recycle aggregate concrete was conducted to study on the effects of recycle aggregate amount, water-binder ratio and fly ash on freeze-thaw durability of recycle aggregate concrete.
